There are 25,000 septic tank systems, approximately 5,000 cesspools, and approximately 1000 class 5 injection wells. Depths of injection wells ranges from 10 to 30 meters. Excessive algal growth, coral diseases and both marine grass and sponge mortality is perceived by the local population, NOAA, and EPA to be caused by sewage nutrients leaking from groundwater on both sides of the Florida Keys. Determining the rate and direction of saline groundwater movement beneath the Key, and the Florida Bay was considered critical to understanding the fate and effects of subsurface waste water disposal n the Florida Keys. The objective of this research was to determine the rate, direction of flow, and contamination levels of saline groundwater in the Florida Keys and Florida Bay. Contamination studies are necessary to determine if nutrient and other contaminant levels are rising and to provide a baseline of data for future decision making.

Samples from all satellite wells were analyzed. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Benchmarks were installed onshore on both sides of Key Largo and position and elevation determined using GPS_Military P-code enabled. Two wells at each cluster were later leveled in using the benchmarks as a reference point. Lineage: Process_Step: Process_Description: Twenty wells were installed to form two (200 ft diameter) circular clusters, each with an injection well in the center. The clusters, located on opposite sides of Key Largo, were designed to determine groundwater flow direction and rate. Each was screened at two depths, (-20 and -45 ft). The following tests were conducted using the well clusters: 1) three separate dye tracer tests using fluorescein and Rhodamine, 2) one test using a colaphage (done in conjunction with University of South Florida) and 3) a single test with Sulfur Hexafluoride (SF6) as the tracer. The first two sets of tests determined flow direction and provided sufficient information to "zero-in" on the actual flow rate. An additional well (100 ft from cluster) was added to each cluster once the direction of movement was determined. The third test (using a combination of dyes and SF6) provided accurate flow-rate estimates. These data facilitated the design of future rate and direction experiments. All wells were continuously cored and cores reside at the St. Petersburg Coastal Center. The well clusters were completed so that all of the piezometers were 100 ft (30.3 m) away from the central well. The central well became the location for the injection of dye to trace the natural gradient of groundwater flow. Fluorescein was injected in the shallow, central piezometer and Rhodamine WT was injected in the deep, central piezometer. The central well for the bayside cluster is approximately 75 m offshore.
